AM Best Affirms Credit Ratings of Berkshire Hathaway GUARD Insurance Companies' Members
AM Best has affirmed the Financial Strength Rating of A+ (Superior) and the Long-Term Issuer Credit Ratings of "aa-" (Superior) of WestGUARD Insurance Company, AmGUARD Insurance Company, EastGUARD Insurance Company, NorGUARD Insurance Company and AZGUARD Insurance Company, which operate under an intercompany pooling agreement. These companies are members of Berkshire Hathaway GUARD Insurance Companies (GUARD) and domiciled in Omaha, NE. The outlook of these Credit Ratings (ratings) is negative.
The ratings reflect GUARD's balance sheet strength, which AM Best assesses at the strongest level, as well as its adequate operating performance, neutral business profile and appropriate enterprise risk management. GUARD's ratings further recognize the implicit and explicit financial support provided by its immediate parent, National Indemnity Company (NICO), a subsidiary of Berkshire Hathaway Inc. (NYSE:BRK), including significant capital support via reinsurance transactions and capital contributions.
The negative outlook reflects the continuation of the sharp deterioration in GUARD's underwriting results that began in the 2023 calendar year and continued through the first quarter of 2025. The decline in underwriting performance has been driven by prior year adverse reserve development in business lines other than the group's core workers' compensation business, which continues to perform solidly. GUARD's significant underwriting losses in 2023, 2024 and 2025 included the impact of material reserve strengthening across several business lines, including commercial auto and business owners' policies (BOP). The group has taken several significant steps to improve its underwriting performance, including discontinuing its underperforming admitted personal lines business and re-underwriting its commercial auto and BOP lines of business. GUARD has also made significant additional investments in systems, internal controls and personnel. AM Best notes that over the past 24 months, GUARD has established an almost entirely new senior leadership team that is tasked with restoring its operating performance to the previously adequate levels.
Potential concerns about GUARD's overall credit profile are mitigated by the group's position as a subsidiary of Berkshire Hathaway Inc., which remains a significant source of financial flexibility and potential liquidity to GUARD. The net impact of GUARD's adverse prior year loss reserve development, while still meaningful, has been greatly attenuated by GUARD's internal reinsurance contracts with NICO. GUARD's capitalization, which has remained consistently supportive of its overall strongest balance sheet strength assessment, benefited from a significant capital infusion from NICO in the second quarter of 2024. AM Best views these examples of explicit support as indications of Berkshire Hathaway Inc.'s continuing commitment to GUARD.
Going forward, AM Best will continue to closely monitor GUARD's progress toward restoring performance metrics to levels that are supportive of its current ratings.
